What are async/await in JavaScript?

Can you explain what async/await is in JavaScript?

Sure! Async/await is a syntax in JavaScript that allows you to work with asynchronous code more easily. It makes your code look synchronous, which can be easier to read and understand.

How does async/await improve the readability of code?

It allows you to write asynchronous code that looks like regular synchronous code. Instead of using then() and catch() methods, you can use the await keyword to pause execution until a promise is resolved.

Can you give me an example of how to use async/await?

Of course! Here's a simple example:

async function fetchData() {
    const response = await fetch('https://api.example.com/data');
    const data = await response.json();
    return data;
}

In this example, fetchData is an async function that waits for the fetch call to complete before proceeding.

What happens if a promise is rejected in an async function?

If a promise is rejected, it will throw an error. You can handle this using try/catch blocks within your async function.
